Answer:

1.02 cm²

Step-by-step explanation:

An equilateral triangle is a triangle with all three sides of equal length.

The perimeter of the triangle made by Lawrence is 18 cm. Which is calculated as follows:

perimeter of equilateral triangle = 3*side

Therefore, each side is 18/3 = 6 cm long

Area of equilateral triangle = √3/4*side²

Area obtained by Lawrence = √3/4*5.8² = 14.57 cm²

Actual area of the triangle = √3/4*6² = 15.59 cm²

Absolute Error = | Measured Value - Actual Value |

Absolute Error = |14.57 - 15.59| = 1.02 cm²

Answer:

Step-by-step explanation:

Work with the two points

Formula

m = (y2 - y1)/(x2 - x1)

Givens

y2 = 3

y1 = 1

x2 = - 2

x1 = - 5

Solution

m = (3 - 1) / (-2 - - 5)

m = 2 / (-2 + 5)

m = 2 / 3

theta is in the fourth quadrant where the cosine is positive.

the third side in the triangle = sqrt (4 - 2) = sqrt2

So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)

tan theta = - sqrt2 / sqrt2 = -1

prohojiy [21]

Answer:

<u>212,400 items</u> were sold in 10 months.

Step-by-step explanation:

Given:

Items sold this month = 70,800

Percent Increase in every month = 20%

We need to find number of items sold in coming 10 months.

Solution:

First we will find number of items increase in each month.

number of items increase in each month can be calculated by Percent Increase in every month multiplied by Items sold this month and the divided by 100.

number of items increase in each month = $\frac{20}{100} \times 70800 = 14,160$

Now we will find number of item sold in 10 months.

number of item sold in 10 months is equal to sum of Items sold this month and number of items increase in each month multiplied by 10.

framing in equation form we get;

number of item sold in 10 months = $70800+10\times 14160 = 212,400$

Hence <u>212,400 items</u> were sold in 10 months.
